Standard adult colonoscopes only will be used. Polyps will be removed with snare polypectomy or biopsy upon withdrawal of the colonoscope from the cecum as is the normal practice. In the event of failure to reach the cecum with the standard adult colonoscope, a variable-stiffness colonoscope (adult or pediatric) will be used (4, 6). In patients with severe stenosing diverticular disease, with difficulty in navigating the affected segment a pediatric variable stiffness colonoscope will be used (5).
